Beit known that i5, WmnIAM'lxFsHnR, a l' States ,fmsiding at 'Philadelphia, in thefceunty 'f EPhilaclelphia1"and'V State of/Pennsylvaniay-have inventedHcertain new and useful Improve;mentsIiii--Jourfollowingis a= specification.

My invention relatesto i joui-nah bearings, and partieularl to bearings supporting both -or shaft as n'buiing-'malchilies Aarfdlind'red apparatus.

' The` base C of'the` lower half ofthfe"box is rearwardly extended'beyond'thebody ofthe boX and there formed with anupwardly-projfectingpost IlE through which an adjusting vscrew V `passes," the end of theadjusting screw f bearing-against they rear `Jface of the block D"Whereby1tli'e-bloc`k may be held in any desired-position, anut lock'lhlbeingvused g isliding to hold the' adjustingscrew set. 'c The block is to be made of chilled steelor iikematerial'having the conical bearing drilled out thereof to` snugly receive thel conical end of -'the spindle. At 4its forward I-endthe base has to each other.' There-are four'bushing seeltions, one jF beingbeneaththe- 's indle;one F3 above and two F', F on'the si' vesfiflhach 'section is provided at its' endsfwitlrutlwardly projecting flanges f, f. i The outsidej measurement of thefinndr Harige f "-'dianretric' all-y across the lnxshing-'is equal tothe width between 'the' Walls C, 0"; andthe 'inner v'end i ofthe bushing is intended to be insertedjbel tween these walls. The'bushing i's'jus't-'sufe depth o the' box, and 'is' cut; out at itscenterl widerspaoe islefty the bushing-sections gradually-closeup-near'- fthe upwardlytprojfecting wall C3 Ywl'iicir-ex- I the iront.

iciently long so as toproject out beyond the inner face of the box as shown in the plan Fi l. 2.

assing through the side walls C" are the screws Gf, two on each side adapted to bear against the side sections F', lf of the lousliing, and to ce adjusted so as to force the side sections inward against the spindle so as to hold the spindle against any lateral play. There are two screws G on each side of the journal box, and hence the two ends of the usliing may be differently adjusted or the bushing may loe accuratel set so that it is in exact parallelism with t e spindle. Each of the adjusting screws G is provided with lock nuts G whereby the screws may be locked in any position to which they are set.

'lhe cover lil of the 'ournal box is adapted to t over the side walls C, C2, and to bear at its lower edge against the base C. The rear or outer end of the cover is open so as to allow the rejection of the block l). 'llie front ci' t ie cover is provided with a downwardly projectin wail H which extends half-way down the cover to meet the upwardly projecting wall C3 of the lower portion oljthe -journal box.

ln order to hold the cover rigidly connected to the lower half of the journal box so that there shall notbe any sidewise movement after the cover is in place, l provide the meeting edges of the cover and of the base on the front of the box with projections and recesses cg, its which enter into each other.

As noted the bushings reject bcyond the front of the box, an the front flange f projects laterally outward against The side walls H2 of the cover are slotted as at 7L for the passage of the screws G and the nuts G.

The cover is provided witlifour bolts I, two on each side adapted to enter bolt holes 'i formed in the upper edge of 'the walls CZ and the base C. 'lhese bolts are for the urpose of fastening the cover down in p ace upon the base. In order to properly lubricate the block D, and the inner face of the bushings l?, l provide oil cupsJ, J', the oil cup J being attached to the cover at a point approximately over the block D, while the oil cup J is located over that portieri of the shaft or spindle which is supported by the bushings l?. These oil cups are of the ordinary construction and have passages therefrom leading tothe inner side of the cover.

'Ille blocn D is grooved as at d2 on its u per face, the groove running longitudinally across the face of the block, the walls of the.

groove'inclining downward towards the cenf ter where a passage d extends to the interior of the conical bearing recess of the block.

The operationof my invention is as follows: As the spindle or the block A wears, the block may be adjusted u by'ineans of the adjustingscrew E andtiis to any exeines-s tent desired, so tiret bearing' may be set to run lia-rd. or easyf-The bearing r A 'within the block D being conical and o of thev si indie being conicaLdtlie weer will constant y center the shaft and the sbs-zit a never get out of center. in order that the weer shall not como upon the end of the spindle and to prevent any lateral thrust, lf. provide the adjustable bushings having the side screws G. v'lhese bushings may lee easily renewed or changed or set by return@ ing the cover of the boxfand may be r slrr and accurately adjusted to suit' the exigen,- cies of running by means of theA screws G which areof course held in, position when sot so by the set nuts G.

My vention provides hedging adapted to be used for shafts'deindridinga high l and accurate support, Tite journal i carry a large amount of oils.n .l .in easily taken apart for inspectiorrlor pa The main element of advantage vention resides however in the'. cacy with which the bea." justed, its centering qua-liti with which the shaft ,or spindle n tated therein., A

lt will be noted that it is not L rernove the cover of the box adjust the block D, and thus Ais running too hard it is a simple met reverse the screw E to a slight dc J releasing the block. D and aliowx move outward, whereas if the ning too loosely it is only n up the screw until the desired arrived at. The cover H entirm the bearing from dirt, yet it may be removed for' adjustment or reuf" the main advantages of the in' the ease with. which the lies' adjusted while the machine without removing the cover.

Having thus described my inv l; claim as new and desire to all , ters Patent is:

1. ln a journal bearing, c.. bush posed of a bottoni and top scot' opposed side sections a het; liar s,

having upwardly projecting sido" r.. an( block mounted at tho'end ci .f section and having s. conical reception of the end ci the i M j in said bushing end mounts-l to incve ine.- pendently of the shaft, screw supported on said base for forcing said block inward against the shaft, ccover adapted to incluso said block and bushings and og up said bese, oiling'openings in "z cover, and adjusting-Y dscrews projecting through the sides of said base and said oever and bearing against the side sections of the bushings.

2. In a journal hearing, a base having upwardlyprojecting sides, the base extend- -portion supporting tlie lower section ci l '.jll

ing laterally beyond said sides, and a rear- Wardly projecting portion having a standard thereon, a sliding bearing block guided between said sides, an adjusting screwpassing through said standard and engaging with said bloc-l1, said block having'a conical recess in its face for the reception of the end of a shaft, a bushing supported between the said sides at the end of said basev opposite the standard, said bushing comprising allower section, a top section and two side sections adjusting screws passing'through the sai sides and engagingwith said side sections of the bushing to force thern inward against the shaft, lock'inuts for holding said screws set, a cover having downwardly projecting., sides adapted to extend downward over the sides of the base portion, said cover and base sides being slotted for the passage of the bushing adjusting screws, bolts for holding said cover in engagement with the base, and oil cups on said cover above the sliding block and the uppermost bushing section,k said block and bushing sections having oil passagesfrorn their surface to the interiorv thereof. A i

3. In a journal bearing, a base, a sliding bearing block mounted in said base having a longitudinal guide-way, base, a block movable in said having a recess to receive the end of a shaft, and an oil inlet duct connectingI said recess with a .longitudinal tape-ring `groove in the lujper end of said block, means for suj'iplying conical recess for the reception of the conical end adjusting said block against the end of a haft, and a cover iitting'over said block and of a shaft, a screw for independently 3U upon said base, said cover being provided -With oil cups opening on the inside of the c'over above the block, said longitudinally extending face, and a passage leading portion of said groove to the interior ol said conical recess.

block having a groove on its upper from the lowest 4. In a journal bearing, a base having a ay cover on said guide-way ricant to said groove, vand ineans for moving the block toward its shaft.

In testimony whereof l have signed nn' name to this specification in the presence vof 50 two subscribing witnesses.
